Description.

Medium size, depressed, rather strongly pubescent (Fig. 1H View Figure 1 ). Head brown with wider, transverse yellowish bands on dorsal field; anterior narrow band curved between ocelli; face short, yellow; clypeus spotted with brown, front with feeble suture (Fig. 2H View Figure 2 ). Pronotum transverse with concave anterior margin; disc almost straight; yellowish with wide brown band along posterior margin and a more or less important spot of the same colour on the impressus (Fig. 4H View Figure 4 ). Elytra extending to 1/3 of abdominal tergite, truncated, rounded at apex; mirror quite apical, little wider than long, rounded posteriorly; wings reduced (Fig. 9B View Figure 9 ). Abdomen brown in the male (Fig. 1H View Figure 1 ).

Male: LH 2.8 ± 0.72 (mm), LP 3.25 ± 0.62 (mm), LT 4.1 ± 5.2 (mm), LF 11.5 ± 1.0 (mm), LT 8.0 ± 0.57 (mm), TBL 14.5 ± 1.0 (mm) Female: LH 2.10 ± 0.8 (mm), LP 3.32 ± 0.72 (mm), LT 4.3 ± 5.7 (mm), LF 12.5 ± 1.2 (mm), LT 8.2 ± 0.62 (mm), TBL 18.6 ± 2.1 (mm).

Ecology.

It commonly found everywhere but surprisingly, a single male only was reported during the present survey. Usually, this species is found in homes and lives under bricks and debris, and also in kitchens.

Global distribution.

Australasia, Australia, Malaysia, West Bengal, USA, India, Pakistan ( Cigliano et al. 2020).

Remarks.

Gryllodes sigillatus is cosmopolitan in nature. This species is generally known as the tropical house cricket or Indian house cricket because they are found everywhere, domestic in all tropical countries. Khan (1954) reported that it caused huge damage to textiles mills in India. During our field survey we observed that this species moves at dusk from the holes of a termite mound. However, this species is not termitophilous in nature like other insects; it does not live with the termites.
